Audio professionals looking for a powered subwoofer that complements the SONAR Xi full-range speakers will be impressed with the HK Audio SONAR 115 Sub D, a compact, active subwoofer with a 1500W peak amplifier that powers the 15" woofer that produces frequencies as low as 40 Hz with a maximum SPL of 128 dB. The SONAR 115 Sub D deliver high-quality sound and a whole catalogue of professional features at an affordable price point.

• The cardioid principle is all about cancelling out frequencies radiated to the rear. While medium and high frequencies can be radiated in directional patterns, low frequencies are spherical. This often leads to an unpleasant excess of low bass on and behind the stage. Organizers are also increasingly setting precise demands for sound distribution, for example, in marquees and urban stages.
• The SONAR 115 SUB D meets all the requirements, both mechanically and acoustically, to implement effective cardioid setups quickly and easily, reducing the low bass radiated to the rear by up to 30 dB. This not only makes performing on stage much more relaxed, but it also results in a better sound, as microphones no longer pick up unwanted low frequencies.
• A second SONAR 115 Sub D can be used to increase the sound pressure level in the bass range. The classic full-stack setup (shown on the left) with two subs projecting forward boosts the sound pressure by level 3 dB in all directions. But what makes the SONAR 115 Sub D so special are its cardioid capabilities. It has two special presets that allow you to configure a cardioid setup, where the lower sub projects to the rear without the need for any complex calculations or time correction.
• To do this, simply direct the lower SONAR sub to the rear and select the Cardioid Rear preset, and direct the upper sub to the front, selecting the Cardioid Front preset. Now both subs can play perfectly together without having to make any further adjustments.

Q: 8. what is max spl output of the svs pb16ultra?

A: The standard for measuring subjectively clean maximum dynamic output is CEA-2010. There are accurate 3rd party measurements available for the PB16-Ultra at the below link. These were obtained outdoors, away from reflective structures, with the mic on the ground plane at a distance of 2 meters. Indoor SPL will naturally be considerably higher than these measurements with boundary reinforcement and room gain considered.a href= https://www.audioholics.com/subwoofer-reviews/svs-pb16-ultra-subwoofer target= _blank https://www.audioholics.com/subwoofer-reviews/svs-pb16-ultra-subwoofer/aEd M - SVS
